CNN Video
Here's the video from Piaget Crenshaw.
Like how she narrates what Officer Wilson must be thinking or talking about. Also helps that the autopsy was released before she released the video. Whereas too many other "witnesses" were found to have lied by claiming Wilson shot MB in the back, she was able to correctly state he was grazed in the arm....hard to see that from her vantage point...and then shot in the front.
Unfortunately, her story is at odds with another person at the scene, a black guy who is overheard on video saying MB rushed at the officer.
Again, if the evidence shows the officer was wrong then he should be arrested and put on trial.
